frame-address, frame-stack-pointer return offsets
* libguile/frames.c (scm_frame_address, scm_frame_stack_pointer): Return
offsets instead of absolute pointers. This is robust in the presence
of stack relocation.
* module/system/repl/debug.scm (print-registers): Adapt to print sp and
fp as integers.
